Abstract
A new testing device for high temperature elastic modulus was designed based on the principle of acoustic resonance, using dynamic link library technology to complete the data acquisition, adopting Labview as the develop platform to realize the function of data acquisition, signal processing, result calculation and document retention. Contrast experiments both in high temperature and normal temperature were made to verify the performance of device. Experiments results showed that the device had accurate testing results and was able to satisfy the testing needs for high temperature elastic modulus.
